Abstract

Abstract:

By the end of 2019,the installed capacity of hydropower units in China has reached 3.564 TW,and the annual power generation is around 1.3 PW·h.Hydropower has become the central pillar of energy structure adjustment.The proposal of carbon neutrality and carbon peak makes it more urgent to solve the problem of renewable energy consumption.The 13th Five-Year Plan for hydropower development makes it clear that the subsequent development of hydropower should concentrate in southwestern regions.Under the new situation,although the abandoned hydropower has been lowered,the continuous decline of electricity price and increasing exploration cost of hydropower seriously restrict the sustainable development of large hydropower projects. In response to this,a reasonable mechanism for sustainable development is discussed combining the current development strategy and macro regulation strategy.It is suggested that,upholding the principle of "allowable cost plus reasonable income",a sustainable hydropower electricity price mechanism "benchmark price + floating price" is cosntructed,which can promote the high-quality development of hydropower energy.

Key words: hydropower exploration, abandoned hydropower in southwestern China, exploration cost of hydropower, sustainable development, renewable energy consumption, carbon neutralization, carbon peak
